Lambando is a fascinating word because it's not a standard Portuguese verb. It was creatively invented for this song, derived from the noun Lambada, the name of the famous Brazilian dance.
The -ando suffix is the Portuguese equivalent of the English -ing ending for verbs. Therefore, Lambando essentially means "dancing the Lambada." The line "Lambando estarei" translates to "I will be dancing the Lambada," perfectly capturing the song's blend of nostalgic sorrow and the joyful energy of the dance.
This song might sound like a party, but the story is all about a breakup! It starts with a fantastic bit of revenge: "Chorando se foi quem um dia só me fez chorar" (Crying, the one who one day only made me cry, has gone). The person who broke the singer's heart is now the one left in tears, full of regret for a love "Que um dia não soube cuidar" (That one day they didn't know how to care for).
Instead of being sad, the singer decides to dance through the memories. They hold on to the good parts, like the "Dança, sol e mar" (Dance, sun, and sea). They'll be "Lambando estarei" (I will be dancing Lambada) while remembering how their love, even if it was short, "Por um dia um instante foi rei" (for one day, one moment, was king). It's a mix of song, laughter, and pain, all wrapped up in an unforgettable dance.
